Disc Brakes

Art's Family Auto Repair Answer:Signs of brake problems often fall into one of two categories for Phoenix vehicles: making noise or a pulsation in the brake pedal. Let's start with the noise.

Most brake pads have an audible brake wear indicator. This is a small piece of metal that rubs on your brake rotor when the brake pads are worn to the point they should be replaced. The noise is a chirp or soft squeal. This noise gives Phoenix drivers enough warning to get their brakes serviced while there is still enough brake pad left to enable you to stop safely.

Phoenix drivers who ignore the chirp find that the sound changes to a grinding noise. That is more serious. It means that the friction material on your brake pad is worn away and metal parts of the brake are grinding against the rotor when you press on the brakes. Obviously, this metal-on-metal means that your brakes aren't stopping very well. It also means that your rotor is being damaged. It may need to be resurfaced or even replaced.

Pedal pulsation is another noticeable sound. When your rotor is not in perfect alignment, it pushes against the brake pads unevenly as you apply the brakes. There could be a number of reasons for this. The rotor and wheel hub may not be mating well, causing the rotor to be spinning out of vertical alignment. This misalignment can be caused by either the rotor or the hub, or a combination of the two. If this persists, the rotor may even start to wear unevenly to the point that its thickness varies, causing an even more noticeable pulsation. This uneven mating of the brake pad and the rotor when braking means less contact and it will reduce braking power.

Your service center or the team at Art's Family Auto Repair in Phoenix can determine the cause of the misalignment and remedy the problem.

Either unusual brake noise or pedal pulsation are signs for Phoenix residents that there are brake problems. Phoenix motorists should have a tech at Art's Family Auto Repair check their brakes thoroughly and recommend any steps necessary to correct the problem.

A regular brake inspection is on every vehicle's recommended list. Ask your friendly and knowledgeable Art's Family Auto Repair service advisor if it's time for brake inspection.
